As far as the pickets and crossing the line, this situation is a bit odd since they aren't unionized. The entire concept of "not crossing the picket line" is for other union workers to stand with their brother and sister union members, by striking with them or at least not continuing to work. But in this situation, there is no union. So there's really no obligation. That being said, it'd be a good gesture for the other workers to stand by them, nonetheless. But I'm sure plenty will continue to work anyway, considering there is no union repercussions for doing such.
